A kidney stones is a hard, crystal-like mass that develops in the kidney. Under normal circumstances, your kidney will collect and dissolve your body’s waste materials and send them to the bladder to be excreted. Kidney stones occur when solid waste materials do not dissolve into the urine. Over time, these materials build up and form kidney stones.

In most cases, kidney stones are passed through the urine without even being noticed. However, stones can become too large to pass and ultimately block the flow of urine, causing severe pain in the back, side, or abdomen. When this occurs, the stone must be treated in order to stop the pain and resume normal urine flow. The most common form of treatment for kidney stones is lithotripsy.

Shock Wave Lithotripsy (SWL) is the most common treatment for kidney stones in the U.S. Shock waves from outside the body are targeted at a kidney stone causing the stone to fragment. The stones are broken into tiny pieces. lt is sometimes called ESWL: Extracorporeal Shock Wave Lithotripsy®.

These are what the words mean:

  • extracorporeal: from outside the body
  • shock waves: pressure waves
  • lithotripsy (the Greek roots of this word are "litho" meaning stone, "tripsy" meaning crushed)

So, SWL describes a nonsurgical technique for treating stones in the kidney or ureter (the tube going from the kidney to the bladder) using high-energy shock waves. Stones are broken into "stone dust" or fragments that are small enough to pass in urine. lf large pieces remain, another treatment can be performed

Robust Performance and Excellent Clinical Results

Medispec’s lithotripsy systems combine one of the highest pressures with the largest focal zones in the industry. Medispec’s large focal zone covers a larger surface area than the other systems, so it is more likely to hit the stone, increasing speed and efficiency in the treatment and superior performance.
